Blue Mage's implementation sucks. But, you aren't worse off for having it.

If they released it like every other job people would complain about them not handling it differently. End of the day SE loses no matter how they do things.

They could also do it as a real support job, thing that never existed on FFXIV (dont know for 1.0 so, i speak for ARR and after)
It would be "not the same thing" aaaaannd... would be a real job added.

And no, this is not a "job different from the other" i dont see any job, i see a side content...
